Thaum cov neeg feem coob hnov 'cov khoom siv hlau txhaj tshuaj molding', lawv tam sim ntawd pom qhov loj, ci iab hlau txhaj molding tshuab nws tus kheej-ib qho nrog lub zog clamping quab yuam tonnage ntawm daim ntawv spec. Qhov ntawd yog thawj qhov yuam kev. Hauv kev muaj tiag, cov xovxwm ntawd tsuas yog qhov pib, thiab sib cav tsis yog qhov tseem ceeb tshaj plaws rau kev ua kom zoo sib xws, muaj txiaj ntsig zoo. Qhov kev ua si tiag tiag yog ua si hauv kev txhawb nqa: cov kab debinding, cov sintering furnaces, thiab cov huab cua tswj systems uas feem ntau cov neeg muag khoom gloss nyob rau hauv lawv cov pitches muag. Yog tias koj lub qhov cub hluav taws xob muaj 20-degree kub qhov chaw, los yog koj qhov hnyav debinding teeb tsis tuaj yeem ua haujlwm ntawm qhov geometry, lub xeev-ntawm-tus-kos duab molding xovxwm yog ib qho khoom kim heev.
Molding Press tsis yog tus Hero
Cia peb tham txog molding xovxwm nws tus kheej. Yog, koj xav tau precision, tswj kev txhaj tshuaj zoo, thiab muaj zog clamp. Tab sis kev xav nrog ultra-siab txhaj tshuaj nrawm? Feem ntau overrated rau MIM. Koj tab tom thawb ib qho khoom noj uas muaj kuab heev, tsis yog yas. Kuv tau pom cov khw nkim nyiaj ntawm servo-tsav txhaj tshuaj units muaj peev xwm ntawm ludicrous speeds, tsuas yog khiav lawv ntawm 30% muaj peev xwm kom tsis txhob jetting thiab sib cais teeb meem. Qhov chaw qab zib yog lub tshuab nrog zoo heev siab profileing thiab kub tswj thoob plaws lub thoob. Ib qho pitfall yog underestimating cov ntaub ntawv hloov lub sij hawm. Yog tias koj khiav 17-4PH ib lub lim tiam thiab 316L tom ntej, koj xav tau ib lub kaw lus uas tuaj yeem ntxuav kom huv thiab ua tau zoo. Residual cross-contamination nyob rau hauv cov ntsia hlau los yog check valve yuav haunt koj nyob rau hauv lub sintering theem, uas tshwm sim li mysterious discoloration los yog tsis muaj zog me ntsis.
Lub clamp kawg tseem ceeb heev, tab sis tsis yog vim li cas koj yuav xav. Nws yog tsawg txog sheer tonnage thiab ntau ntxiv txog parallelism thiab platen rigidity. Ib me ntsis deflection thaum txhaj tshuaj tuaj yeem ua rau me me tab sis tseem ceeb hloov pauv hauv qhov ntom ntom, uas ua rau muaj kev cuam tshuam loj thaum lub sij hawm sintering.
